Temporary Security Barriers AHA (Activity Hazard Analysis / Job Hazard Analysis)
Updated 2026-06-23
A Temporary Security Barriers AHA (Activity Hazard Analysis / Job Hazard Analysis) is the plan that keeps the crew installing temporary security barriers safe in the heavy-barrier placement and rigging, sound in the vehicle-impact rating and security function, and safe in the stability and installation. Temporary security barriers install the temporary anti-vehicle and security barriers that protect a site or area — combining the heavy-barrier-placement and rigging hazard, the vehicle-impact-rating and security-function hazard, and the stability-and-installation hazard. This guide walks through building a Temporary Security Barriers AHA that names the heavy-barrier-placement/rigging, vehicle-impact-rating/security-function, and stability-and-installation hazards and assigns the placement, rating, and stability controls that hold up in the field.
Why temporary security barriers needs its own AHA
Temporary security barriers install and maintain the temporary security and anti-vehicle barriers — concrete barriers (Jersey/K-rail), crash-rated barriers, bollards, and vehicle barriers — that protect a site, building, or area from vehicle intrusion, hostile-vehicle threats, or unauthorized access, especially at federal/high-security facilities. The defining features are the heavy barriers (concrete barriers and crash- rated units are very heavy, requiring rigging to place) and the security function (the barriers must actually stop the threat they are rated for, especially vehicle impact). The hazards combine the heavy-barrier-placement and rigging (security barriers (concrete barriers, crash-rated units) are heavy — placing them requires rigging/ craning/handling the heavy barriers (the rigging and heavy-load hazards)), the vehicle-impact-rating and security-function (crash-rated security barriers must actually stop the rated vehicle threat — an inadequate, improperly installed, or under-rated barrier fails its security function (a serious security safety issue at high-security facilities)), the stability-and-installation (the barriers must be properly installed, anchored/ positioned, and stable to perform (and to not be a hazard themselves)), and the site/traffic. The heavy-barrier-placement/rigging and the vehicle-impact-rating/security-function justify a dedicated AHA.
Breaking temporary security barriers into steps
The steps for a Temporary Security Barriers AHA follow the security barrier:
- Plan the security barriers for the threat and rating
- Rig and place the heavy barriers
- Install and anchor per the crash-rating requirements
- Verify the security/impact rating is met
- Establish the secured perimeter
- Manage the placement, rating, and stability hazards
- Maintain the barriers
- Remove/reposition safely
Each step carries a hazard, and the heavy-barrier-placement/rigging, the vehicle-impact-rating/security-function, and the stability-and-installation are where the most significant risks concentrate.
The hazards step by step
Heavy-barrier-placement and rigging
Security barriers (concrete barriers, crash-rated units) are heavy — placing them requires rigging/craning/ handling the heavy barriers (the rigging and heavy-load hazards). The controls are a rigging/lift plan for the heavy barriers (rated rigging/equipment, verified weights), exclusion zones, controlled placement, safe handling, and the placement/rigging controls. The heavy-barrier-placement/rigging is a defining hazard. (These follow the lifting/rigging fundamentals.)
Vehicle-impact-rating and security-function
Crash-rated security barriers must actually stop the rated vehicle threat — an inadequate, improperly installed, or under-rated barrier fails its security function (a serious security safety issue at high-security facilities). The controls are barriers rated for the threat (correct crash rating for the vehicle threat), installing per the crash-rating requirements (rating depends on correct installation — anchoring, foundation, configuration), verifying the installation meets the rating, and the rating/security controls. The vehicle-impact-rating/ security-function is a defining safety function — the barrier must stop the rated threat. (These follow the crash-rated-barrier fundamentals.)
Stability-and-installation
The barriers must be properly installed, anchored/positioned, and stable to perform (and to not be a hazard themselves). The controls are proper installation and anchoring/positioning (per the barrier and its rating), ensuring stability (barriers that can tip or shift are a hazard and fail their function), verifying the installation, and the stability/installation controls. The stability-and-installation is a defining hazard. (These follow the barrier-installation fundamentals.)
Site/traffic
The site and traffic (installing among site traffic, the barriers affecting traffic) carries the site/traffic hazard. The controls are managing the site traffic during installation, traffic considerations for the barrier placement, and the site/traffic controls. (These follow the traffic-control fundamentals.)

Heavy-barrier rigging safety and impact-rating/security function
A Temporary Security Barriers AHA centers on heavy-barrier rigging safety and impact-rating/security function. The heavy-barrier rigging safety addresses placing the heavy barriers — controlled by a rigging/lift plan (rated rigging/equipment, verified weights), exclusion zones, controlled placement, and safe handling. The impact-rating/security function addresses the barriers' protective purpose — controlled by barriers rated for the threat (correct crash rating), installing per the crash-rating requirements (anchoring, foundation, configuration), and verifying the installation meets the rating, since the barrier must stop the rated threat. And the stability and site get installation and traffic controls. An AHA built on heavy-barrier rigging safety and impact-rating/security function, with stability controls, addresses the hazards that define temporary security barriers.
From the field: what actually goes wrong
In fourteen years across federal, heavy civil, and industrial projects — including federal and high-security facilities — temporary security barriers have a dual character: the physical hazard of placing very heavy barriers, and their function as security controls that must actually stop the threats they are rated for. The heavy-barrier-placement and rigging hazard is the first physical concern — security barriers, whether concrete Jersey/K-rail or engineered crash-rated units, are very heavy, so placing them requires rigging, craning, and handling heavy loads, bringing the rigging and heavy-load hazards. So a rigging and lift plan for the heavy barriers (rated rigging and equipment, verified weights), exclusion zones, controlled placement, and safe handling are the controls. Placing heavy security barriers is a real rigging operation.
The vehicle-impact-rating/security-function and the stability-and-installation are the other defining hazards, and the rating is the one that makes security barriers different from ordinary barriers. On the projects I have run at secure facilities, crash-rated security barriers must actually stop the rated vehicle threat — they are engineered and tested to stop a specific vehicle at a specific speed (an anti-ram function), which means the barrier's security function depends entirely on it being the correct rating for the threat and being installed exactly per the crash-rating requirements. A crash-rated barrier's rating is only valid if it is installed correctly, because the rating depends on the anchoring, foundation, and configuration — an under-rated barrier, or a correctly rated barrier installed incorrectly, fails its security function, which at a high-security facility is a serious security and life-safety issue (the barrier is there to stop a hostile vehicle). So barriers rated for the actual threat, installing per the crash-rating requirements, and verifying the installation meets the rating are the controls. The stability and installation (barriers must be stable and properly positioned — a barrier that can tip or shift is both a hazard and a failure of its function) and the site traffic during installation round it out. The AHA built on heavy-barrier rigging safety and impact-rating/ security function is the one that protects the crew and preserves the security function.
The bottom line
A Temporary Security Barriers AHA names the heavy-barrier-placement/rigging, the vehicle-impact-rating/security- function, and the stability-and-installation hazards with specific controls — a rigging/lift plan for the heavy barriers, barriers correctly rated for the threat and installed per the crash-rating requirements (the barrier must stop the rated threat, a security safety function), and proper stable installation. The heavy-barrier rigging and the impact-rating/security function are the defining concerns. The AHA that manages both is the one that protects the crew and preserves the security function.
Frequently asked questions
Why does the crash rating depend on correct installation?
A crash-rated security barrier is engineered and tested to stop a specific vehicle at a specific speed (an anti-ram function), but the rating is only valid if the barrier is installed exactly per the crash-rating requirements, because the rating depends on the anchoring, foundation, and configuration — a correctly rated barrier installed incorrectly fails its security function. Controls are barriers rated for the threat (correct crash rating for the vehicle threat), installing per the crash-rating requirements (anchoring, foundation, configuration), verifying the installation meets the rating, and the rating/security controls.
What rigging hazards apply to security barriers?
Security barriers (concrete Jersey/K-rail, crash-rated units) are very heavy, so placing them requires rigging, craning, and handling heavy loads, bringing the rigging and heavy-load hazards. Controls are a rigging/lift plan for the heavy barriers (rated rigging/equipment, verified weights), exclusion zones, controlled placement, safe handling, and the placement/rigging controls.
Why does stability matter for security barriers?
The barriers must be stable and properly positioned to perform their function — a barrier that can tip or shift is both a physical hazard and a failure of its security function (it will not stop the threat if it moves). Controls are proper installation and anchoring/positioning (per the barrier and its rating), ensuring stability, verifying the installation, and the stability/installation controls.
What are temporary security barriers?
Temporary security barriers install and maintain the temporary security and anti-vehicle barriers — concrete barriers (Jersey/K-rail), crash-rated barriers, bollards, and vehicle barriers — that protect a site, building, or area from vehicle intrusion, hostile-vehicle threats, or unauthorized access, especially at federal/high-security facilities. Because the barriers are heavy (rigging) and must stop the rated threat (security function), the placement/rigging, impact-rating, and stability hazards apply.
